Four people face cocaine trafficking charges after Sarnia police stopped a suspect vehicle near Highway 402 Wednesday night.
Police say during surveillance, vice unit officers allegedly saw suspects conducting drug transactions and, as a result, decided to pull over a vehicle at the 402 off-ramp at Christina Street at around 8:30 p.m.
Cst. John Sottosanti said four occupants in the vehicle were arrested.
"Upon a search of the accused individuals and the vehicle, officers were able to locate approximately 62 grams of crack cocaine with a street value of $6,200, one gram of heroine with a street value $500, and $1,350 in cash."
Charged with possession and drug trafficking are Robin Alexander Maness, 40, Lil-Star Nahmabin, 41, Carly Rae Timms, 30, all of Sarnia, and Owen Clarke, 34, of London.
They were being held for bail hearings.
